In Germany, they say "Passt wie Arsch auf Eimer", which literally translates as "Fits like an ass on a bucket".
That was the first thing I thought when I saw this picture.

...Her ass is bigger then the bucket

Is no one going to ask WHY she's stuck her ass on a bucket?

obviusly she's going to take a dump.

Deleting files, another reason to get a hard-on.
